No account required, no cloud, no tracking — your fasting data stays on your device, always. WHAT YOU GET - Track every fast with precision: 16:8, 18:6, 20:4, OMAD, 5:2, or your own custom schedule. - See exactly what's happening in your body: progress through fed, fat burning, ketosis, and autophagy phases. - Stay motivated with streaks, milestones, and home screen widgets that keep your current fast one glance away. - Syncs with Apple Health (optional) — your fasting sessions are saved locally and can be written to Apple Health if you enable it.
